One of our fans who goes under the nickname erwtj3 discovered this optical illusion poster below. It was used as an ad for some kind of candy product. Once you learn the tagline behind this poster, itβs much easier to see the illusion it hides. The tag-line went something like this: βIf you love liquorice, all you see is Pandaβ! Now hurry, and be the first to spot the hidden animal in this idle surrounding below! You can see the original poster, one including tag-lines and candies β here.
